The fusebox only needs to be replaced if it shows signs of overheating, other physical damage or doesn’t have any RCD protection of circuits, particularly those supplying equipment outdoors. It would also need replacing if new circuits were being installed that required RCD protection and the existing fusebox doesn’t have RCD protection.
Ask your registered electrician to fully justify the reasons why you need a new fusebox. You can find one local to you here.
